I'd agree, Dillinger, but add an "excessive" to your sentence before the word "carbs" I eat 180g carbs and the vast majority of my tests are between 4.0 and 7,0. I've found that having an advance bolus (different times for different meals) means I can often reduce my bolus and spike in the 6s. It took me time to work out that out, but it means smoother sugars and less thought. I do have a pump though, and that makes it easier in that I know my basal dose pretty closely matches my needs. However, intelligent bolusing (well, as intelligent as I can get it : D ) has been what I've found most useful.
